Definitions

  • the invention generally relates to a power source connecting device having current transformer and, particularly, to a power line connecting device having automatic on/off linked function and externally connected sockets.
  • the personal computer always need to work together with other peripherals, such as printer, scanner, modem, screen, ...., etc., to achieve a specified requirement. Therefore, the total power consumption of the computer main unit (approximately 150 W) with the operation of other peripherals will be raised. Particularly, after shut-off of the computer main unit, all of other peripheral apparatuses are still connected to a power source connecting device, for example an extension line, and not to be used. The power might be wasted since these apparatuses are not used and are at stand-by mode or still at power-on mode.
  • a power source connecting device for example an extension line
  • the power source connecting device as in the form of a power saving extension line is based on the switching type.
  • the switching type of the conventional power source connecting device should be added other parts.
  • the cost and heat dissipation might be another problem, and the possibility of failure-and hazard caused by heat dissipation can be increased accordingly.
  • the sockets are always lined up on a surface of the connecting device for receiving the plug-in.
  • the modern electronic product might not have adapter built in the main body of the electronic product. Therefore, several of adapters being put into the conventional extension line crowdedly might cause loose or poor contact problem resulting in inconvenience and hazard phenomena happened in use.
  • current-transformed power source connecting circuit device comprising: a power source input terminal, in connection with an external power source; a current transformer, including a primary and a secondary windings, the primary winding of which is connected to a circuit in between a main output terminal and the power source input terminal in series, wherein one end of the main output terminal is connected to the current transformer and the other end of that is externally connected to a main load; a rectifying means, in connection with the secondary winding of the current transformer, for rectification of a current from the current transformer; a switching means, for receiving a voltage from the rectifying means, which is switched on at a time that the received voltage is held at a preset value and switched off at a time that the voltage is lower than the preset value; and at least one subsidiary out terminal, in connection with the switching means and in parallel-connection with the main output terminal, for connecting to other external loads.
  • the current-transformed power source connecting circuit device additionally includes at least one current-limiting circuit breaker means which is connected in between the power source input terminal and the current transformer for automatically cutting off a passing current which is too large in excess of a preset value, wherein the current-limiting circuit breaker means can be recovered to an on state by using a manual or an automatic manner.
  • the current transformer additionally includes a regulating switch for regulating a magnitude of current of the secondary winding.
  • a power source extension line which comprises: a power source input plug-in, capable of connecting to an external power source; an electricity distribution panel, including a housing and a wiring board which is installed in the housing; and a plurality of externally connected sockets, for distributing electricity from the power source input plug-in to loads to be connected through the distribution panel, wherein the plurality of externally connected sockets are flexible connecting lines, one end of each line is connected to the electricity distribution panel and the other end is extended to external of the housing. Since the sockets of the power source extension line of the invention are not made on the external surface of the housing of the electricity distribution panel as the same as those of the conventional extension line. Therefore, the crowded problem and interference problem among the transformers, which would cause these sockets not to be plugged well, can be avoided.
  • a current-transformed power source extension line device comprising: a power source input plug-in, capable of connecting to an external power source; a current transformer, including a primary and a secondary winding, the primary winding of which is connected to a circuit in between a main output terminal and the power source plug-in, wherein one end of the main output terminal is connected to the current transformer, and the main output terminal can be connected externally to a high power load; a rectifying means, in connection with the current transformer, for rectification of a current from the current transformer; a switching means, for receiving a voltage from the rectifying means, which is switched on at a time that the received voltage is held at a preset value and switched off at a time that the voltage is lower than the preset value; and a plurality of subsidiary output terminals, for connecting with the sockets respectively and connecting to the switching means, and in parallel-connection with the main output terminal, which is capable of connecting to other loads externally.
  • the current-transformed power source connecting device includes: a current transformer T1 which has a primary winding and a secondary winding, one end of the primary winding is connected with a main load socket AC 2; a current-limiting circuit breaker S1, one end of which is connected to the other end of the primary winding for receiving a passing current, and which can be automatically broken when the passing current is larger than a preset current and can also be automatically recovered after the passing current is recovered back to be equivalent to or lower than the preset current; a current-limiting circuit breaker S2, one end of which is connected to the other end of the circuit breaker S1 and the other end of which is connected to a power source socket AC 1 for bearing a current that is larger than the preset current of the circuit breaker S1, the circuit breaker S2 will be automatically broken as soon as the current is in excess of the preset current and however shall be recovered by manual operation; a current value selector S3, for selection o-f the wounded coil turns of the secondary winding of the current
  • One end AC IN C of the relay U1 is connected with the other ends of sockets A3 to A8, and the other end AC IN D of that is connected to the relays S1, S2 in common.
  • control action is carried out by the magnitude of the current flowing through the primary winding of the current transformer T1, that is not controlled-by the voltage of transformer as the prior art.
  • current of the main socket AC 2 is set lower than the limit of 2 amperes which is preset for the relay S1 in order to keep an electrical apparatus working normally.
  • the typical current transformer is generally connected in series within the circuit loop, in that copper wires of the primary winding are thicker than those of the secondary winding and the turns of wounded coils of the primary winding is less than that of the secondary winding a large number of times.
  • the principal function of the current transformer is to convert an input large current into a small current.
  • Fig. 2 is a 3D perspective view showing a real product appearance of an extension line according to a power line connecting circuit device of the invention, in that the reference numerals of constituents correspond to those defined in the circuit diagram of Fig. 1 and have the same function.
  • Fig. 3 is an exploded view for Fig. 2, showing an extension line in that each component of Fig. 2 is assembled in a housing to become a type of the extension line.
  • the main object of Fig. 3 is to show a relationship of the spatial position between these sockets A3 to A8 and the housing in assembly.
  • these components is collectively arranged behind a wiring board 7 and fixed on a central board.
  • the housing includes an upper cover 4 and a lower cover 6 which are connected in together by using fixing member, such as screws 15 for forming an internal space in order to accommodate the power line connecting device of the invention.
  • these parallel-connected sockets A3 to A8 are extended to external of housing via conduction lines B3 to B8, from the upper housing 4 or lower housing 6, that is, from the upper housing 4 or lower housing 6 in parts, or from the position of the central board 5 to a distance. Since the position among these sockets A3 to A8 can be flexibly varied to be adaptive for different size of the external electrical apparatuses, therefore, the disadvantage of interference among these sockets can be eliminated. That is, the concept of the invention is fully different from that of the conventional sockets which are fixed on the surface of the housing directly. For example, due to the mass production, the power supply is often independently arranged and utilizes the adapter for substitution. By using the conventional extension line, it is possible to cause inconvenience for these adapters to be plugged in.
  • the invention employs external-lead- connection socket such that the actual application of the invention can be preferably matched to the adaption as well as is well-to-do in space, because the invention uses the external leads as a buffer.
  • the plug-in AC 1 When it plans to use the invention for apparatus such as computer and its peripherals, firstly, the plug-in AC 1 is plugged in a socket which can supplies a power source, and the exposed switch S2 can be switched-on by manual manner.--When a main computer (not shown) which is connected to the socket AC 2 is turned on, the current coming from the power source flows through a surge absorber C1 which is to prevent hazard from the surge and through the protection switch S1 to the current transformer T1.
  • the current value setting switch S3 can be set up on first step, for example, in order to match to a power consumption of one computer.
  • two contact DIN 1, DIN 2 of the secondary winding of the current transformer are connected to a bridge rectifier D2, respectively, and AC voltage coming from the socket AC 1 can be rectified by using the bridge rectifier and converted to DC voltage, for example 12V, by using a Zener diode D1 and a rectifying capacitor C2, so as to keep the operation of the relay U1.
  • the terminal AC IN B is conducted with the AC IN C, thus the plurality of parallel sockets AC 3 to AC 8 can be conductive for supplying the electricity to each of electrical apparatus which is connected to the corresponding socket AC 3 to AC 8.
  • the extension line of Fig. 2 was manufactured based on concret design data and estimated the degree of power saving, in order to develop the worth of the invention in industry.
  • Switching mode Current-transformed mode Power-on 4 W (ref. value) 0.67 W Power-off 2 W (ref. value) 0.003 W EMI Noise yes No Cost High (more parts) Low (less parts) Temperature High Low
